python - 在python中使用正则表达式排除模式

Question

我想从给定的字符串中提取 Name 和 number 并将其保存到两个列表中。

    str = 'Dhoni scored 100 runs and Kohli scored 150 runs.Rohit scored 50 runs and Dhawan scored 250 runs .'

我想实现:

    name = ['Dhoni','Kohli','Rohit','Dhawan']
    values = ['100','150','50','250']

我尝试使用负面展望，但没有成功。我试图使用这种方法来匹配一个词，然后是一个数字，然后是一个词。可能是我在这种方法上错了。如何做到这一点？
我试过的:

   pattern = r'^[A-Za-z]+\s(?!)[a-z]'
   print(re.findall(pattern,str))

Answer 1

您可以改用 2 个捕获组:

\b([A-Z][a-z]+)\s+scored\s+(\d+)\b

regex demo

import re

pattern = r"\b([A-Z][a-z]+)\s+scored\s+(\d+)\b"
str = "Dhoni scored 100 runs and Kohli scored 150 runs.Rohit scored 50 runs and Dhawan scored 250 runs ."

matches = re.finditer(pattern, str)
name = []
values = []
for matchNum, match in enumerate(matches, start=1):
    name.append(match.group(1))
    values.append(match.group(2))

print(name)
print(values)

输出

['Dhoni', 'Kohli', 'Rohit', 'Dhawan']
['100', '150', '50', '250']
